Method for manufacturing coconut based activated carbon polyester fiber with high percentage of carbon and the coconut based activated carbon polyester fiber made by the method

ABSTRACT

A method for manufacturing coconut based activated carbon polyester fiber with high percentage of carbon includes the steps of: mixing 5 wt %˜15 wt % (weight percentages) coconut based activated carbon particles which have sizes smaller than 7 μm with 85 wt %˜95 wt % polyester fibers by high temperature so as to get spinning fabrics which are in melted form; extruding and ejecting the spinning fabrics to pass through a fabric ejection plate so as to form a melt ejection flow; forming an initial fiber: cooling the ejection flow leaving from the fabric ejection plate in lower temperature and with a high speed to form an initial fiber; and extending, coating oil, activating, drying, shaping, and packaging to form coconut based activated carbon polyester fibers with high percentage of carbons. A coconut based activated carbon with high percentage of carbon manufactured by the method is also included.

FIELD OF THE INVENTION

The present invention relates to activated carbon polyester fiber, andparticularly to a method for manufacturing coconut based activatedcarbon with high percentage of carbon and the coconut based activatedcarbon polyester fiber made by the method.

BACKGROUND OF THE INVENTION

Polyester fiber has many advantages and thus it is widely used in manyfields including human life and industries.

However, in the manufacturing process of polyester fiber, many differentmaterials are added thereto for satisfying various demands. Thepolyester fiber added activated carbon has high adhesion and highfiltration.

In the prior art activated carbon polyester fiber, 0.1 wt %˜4 wt %(weight percentages) activated carbon particles is mixed with 96 wt %99.1 wt % polyester fibers. However, in this prior art, the ratio of theactivated carbon is very low. It cannot absorb and filer the dust inair. Thereby the sizes of the activated carbon particles are between 150μm˜38 μm. The activated carbon cannot well adhere to the polyesterfiber. Thus in washing the clothes and trousers with the activatedcarbon polyester fiber, the activated carbon will drop down.

SUMMARY OF THE INVENTION

Accordingly, the primary object of the present invention is to provide amethod for manufacturing coconut based activated carbon polyester fiberwith high percentage of carbon and the coconut based activated carbonpolyester fiber made by the method.

To achieve above objects, the present invention provides a method formanufacturing coconut based activated carbon polyester fiber with highpercentage of carbon; the method includes the steps of: mixing 5 wt %˜15wt % (weight percentages) coconut based activated carbon particles whichhave sizes smaller than 7 μm with 85 wt %˜95 wt % polyester fibers byhigh temperature so as to get spinning fabrics which are in melted form;extruding and ejecting the spinning fabrics to pass through a fabricejection plate so as to form a melt ejection flow; forming an initialfiber: cooling the ejection flow leaving from the fabric ejection platein lower temperature and with a high speed to form an initial fiber; andextending, coating oil, activating, drying, shaping, and packaging toform coconut based activated carbon polyester fibers with highpercentage of carbons. A coconut based activated carbon with highpercentage of carbon manufactured by the method is also included.

The various objects and advantages of the present invention will be morereadily understood from the following detailed description when read inconjunction with the appended drawing.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is a schematic view showing the manufacturing process of thecoconut based activated carbon polyester fiber of the present invention.

DETAILED DESCRIPTION OF THE INVENTION

In order that those skilled in the art can further understand thepresent invention, a description will be provided in the following indetails. However, these descriptions and the appended drawings are onlyused to cause those skilled in the art to understand the objects,features, and characteristics of the present invention, but not to beused to confine the scope and spirit of the present invention defined inthe appended claims.

Referring to FIG. 1, the manufacturing process of coconut basedactivated carbon polyester fiber is illustrated. The method of thepresent invention comprises the following steps of:

Mixing: mixing 5 wt %˜15 wt % (weight percentages) coconut basedactivated carbon particles which have sizes smaller than 7 μm with 85 wt%˜95 wt % polyester fibers by high temperature so as to get spinningfabrics which are in melted form.

Ejecting: Extruding and ejecting the spinning fabrics to pass through afabric ejection plate so as to form a melt ejection flow.

Forming an initial fiber: cooling the ejection flow leaving from thefabric ejection plate in low temperature and with a high speed to forman initial fiber;

Shaping: extending, coating oil, activating, drying, shaping, andpackaging to form coconut based activated carbon polyester fibers withhigh percentage of carbons.

By above mentioned processes, the coconut based activated carbonpolyester fibers have particle sizes smaller than 7 μm which arebeneficial to make products, such as cloth, trousers, etc. In thepresent invention, the coconut based activated carbons are adhered tothe polyester fibers firmly. Thus, even in washing, the coconut basedactivated carbon will not fall down. Furthermore since the particlesizes of the coconut based activated carbon are smaller than or equal to7 μm, the percentage of the coconut based activated carbon can beincreased to 5% ˜15% so as to have preferred filtering and adhesioneffect. This can not be achieve by prior art polyester fiber.

The present invention is thus described, it will be obvious that thesame may be varied in many ways. Such variations are not to be regardedas a departure from the spirit and scope of the present invention, andall such modifications as would be obvious to one skilled in the art areintended to be included within the scope of the following claims.
